Specification of Letters Patent. Application filed December 6,

Patented Oct. 27, 1914. 1912. Serial No. 735,291.

To all whom it may concern.'

ylie it known that l, HAPRY L. VILLIAMS, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Swinging-.Sash lVindows, of which the following is a speci-` fication. i d

The invention relates to windows in which the sash is vertically pivoted either in the `middle or at the sides of the frame, and to a rocking Z bar is provided on the window sill to close and lock the joint between the sill and the sash when the window is closed. The object of the invention is to provide suitable means for mounting and manipu* lating the rocking Z bar for a most efficient and positive performance of its functions as a lock and a closure, and to prevent an accidental displacement of the bar in either its opened or closed relation and `furthermore to provide means for locking the sash when opened to various angles from its closed position.

rlhe objects of the invention `thus set forth in general terms are attained by the pre-` ferred embodiment thereof illustrated in the accompanying drawings, forming part hereof, in which:-` Figure 1, is an inside view of a centrally-j pivoted swinging-sash window showing the improved devices applied thereto; Fig. 2, a vertical section of the same on line 2-f-2, Fig. l; Fig. 3, a transverse section of the same on line 3-3, Fig. l; Fig. 4, a vertical detail section showing the improved locking devices on line 4fi, Fig. l; Fig. 5, a perspective view of the several parts of the operating devices in relative position for assembling; Fig. 6, a fragmentary plan view of the window with the sill plate broken away and showing the crank disk, the pit` man and the guide bar in open relation; F ig. 7, a similar view showing the same parts in closed relation; Fig. 8, an under side perspective view of the closure bar.

Similar numerals refer to similar parts throughout the drawings.

ln this class of windows, the sill bar l is secured on the sill proper 2, and rises above the sill stool 3, so that the lower sash bar 4t will swing free of the stool. The sill bar is provided with the longitudinal Vl shaped channel 4 to receive the web 5 and .nel 4, and are located slightly inner flange G of the closure bar, when the same are rocked downward inopen position, as shown in Fig. 2; and the edge of the lower sash bar is provided with the longitudinal inverted V shaped groove '7 `to receive the inner flange G of the closure bar, when the same is rocked upward in closed relation.

A series of hinge plates 8 are recessed` and secured in the bottom of the sill-bar chanprovided with the pintles 9 n above the forward edge `10 of the sill bar, upon which pintles the angle `11 between the web 5 and forward flange l2 of the closure bar is adapted to rock,"

preferably free of said forward edge;` and a series of hingeplates 13 are secured to the lower side of the web 5 of the closure bar, and are provided with the bearings lil which engage under the pintles 9` to complete the hinge joint thus formed between the forward angle l1 of the closure bar and the forward edge 10 of the sill bar.

d The pitinan :15 is composed of the plate l5 and the adjusting bar 15b screwed into the forward end thereof. The `forward end ofthe adjusting bar is connected with the forward `flange 12, ofthe closure bar by the ball `and `socket joint 1G, and the rear end of thepitman plateis laterally widened and provided with the transversely` elongated slot 17. The U shaped guide bar 1S is engaged by the `dowel `pins 19 with the sill stool, and the arms of this bar form guides l for the pitinan plate and serve to hold the same in proper longitudinal alinement.

The disk crank 20 rests and rotates upon the curved yoke end of the guide bar as a bearing, and is provided with a central pivot post 21011 its upper sidc,the eccentric pivot pin 22 on its lower side, and the operating arm 23 extending from one peripheral edge. The plate 24 is engaged with and secured to the sill by the dowel pins 25 and screws passed through the apertures 2G. This sill plate arches over the disk crank, and is provided in its under side with the bearing socket 27 for the central pivot post 21, of the disk crank; and when `a centrally pivoted sash is used, as shown, the sill plate is also provided with the pivot post 28 and the lock sockets 29, 29 and 29", on its upper side.

The plate 30 is secured on the inner side of the lower sash bar and is preferably provided in the lower end of the sash-plate flange 31 and forms the lower pivot bearing for the sash.

The bolt crank` 33 is located von the inner side of the sash plate 30; its pivot shank 3Ay is journaled in the plate and extended rearward therefrom. The curved bolt 35 is mounted on the extended portion ot' the pivot shank, which is preferably squared to receive the bolt, and is furthermore provided with the retaining pin 36 on its ree end and a spiral compression spring 37 between the pin and thel bolt, to press the saine against the sash plate and rictionally hold it in a given position of rotation.

l/Vhen the parts are assembled the bolt is adapted to be rotated by its crank to engage its i'ree end into one of the bolt sockets in the sill plate, to positively hold the sash at a desired angle of rotation. To increase the bearing of the bolt on the sides of the sockets, the raised ribs 38, 38a, 38b and 38c are preferably provided on the sash plate between the sockets, and the first lug 38 on each side is inclined so that if the free end of the bolt should be depressed when the window is closed, the inclined rib will throw the saine upward to clear the other ribs, in which position the bolt is frictionally held by the compression spring until it is forced into one of the sockets by a positive rotation of the crank. Likewise, when the free end of the bolt is disengaged from a socket, by a rotation of the crank, the bolt will be held above the ribs by the same spring while the window is being swung to and fr0.

The closure bar is rocked upon its pivots from its closed to its open position and vice versa, by a rotation or' the disk crank;

and the parts are so proportioned and arranged that when the closure bar is rocked into open position, the operating arm 23 will stand at right angles on one side of the pitinan, as shown in Fig. 6, and when the closure bar is rocked into closed position the operating arIn will stand at right angles on the opposite side of the pitrnan, as shown in Fig. 7. Furthermore, the crank-disk pivot-post is located in the axial line of the pitinan, and the pivot pin is so located that it will be in the saine axial operating arm is thrown into each of the open and closed positions, being in front of the pivot post in the open position and in the rear thereof in the closed position, as

illustrated in Figs. 6 and 7. Froin this arrangement of the parts it is evident that the closure bar will be locked when it is in closed position and also when it is in open position, thus preventing an accidental rocking of the bar from its open position into the path of the sash door, without ay positive operation of the operating bar.

'I claim A window including a vertically-pivoted swinging-sash, a sill-stool with a sill-bar on the outer side thereof, a Z-shaped closure bar having one angle pivotally secured on the outer edge of the sill-bar and the adjacent flange swinging in open and closed re lation on the outer side thereof, and operating lneans for rocking the closure bar upon its pivoted angle.
